@Vahid Bayat 1. Regarding the point about speculative positions versus hedging positions: Yes, that’s correct. However, that’s the topic of another post I plan to write soon. In that post, I'll address distinguishing between directional buyers or sellers and hedged buyers or sellers, and only consider positions that reflect the strategies of directional market participants. In this post, though, I want to focus on the topic of determining probabilities using the Delta parameter. 2. Regarding the need for potential modifiers: Yes, that's certainly something we should consider. However, as mentioned, this is a topic for another post. 3. Regarding the Skew: I didn’t quite understand this part. I’m not sure how by itself, it can be interpreted as a signal or standard deviation. 4. Regarding the suggestion to make the data smart and selective: Yes, that’s correct. However, that’s quite complex. For now, we're trying to collect and store good data. In the next steps, we can then selectively and smartly gather and evaluate data from various sources.
